 a plurality of air inlet tubes arranged horizontally and equidistantly within the sides of the outsole; 
 a transfer tube connecting the air inlet tubes; 
 a flexible insole disposed within the bounds of the outsole; 
 a heel chamber in a heel area of the insole; 
 a front chamber in a front area of the insole; 
 a plurality of mini chambers arranged throughout the insole; 
 a transfer channel connecting the heel chamber, front chamber, and mini chambers; 
 an air inlet at a rear of the insole; the air inlet connecting the heel chamber to ambient air; 
 an adjustably opened valve within the air inlet. 
 
   
   
     6. The invention in  claim 5  wherein the insole is composed of memory foam. 
   
   
     7. The invention in  claim 5  wherein the air inlet further comprises a one-way check valve, whereby air is allowed into the air inlet. 
   
   
     8. The invention in  claim 6  wherein the air inlet further comprises a one-way check valve, whereby air is allowed into the air inlet. 
   
   
     9. The invention in  claim 7  wherein the adjustable opened valve is exterior to the check valve. 
   
   
     10. The invention in  claim 8  wherein the adjustable opened valve is exterior to the check valve. 
   
   
     11. The invention in  claim 6  wherein the adjustably opened valve is removable. 
   
   
     12. The invention in  claim 7  wherein the adjustably opened valve is removable.
